For a reaction `R to P`, the concentration of a reactant changes from 0.05 M to 0.04 M min 30 minutes. What will be average rate of reaction in minutes?
A. `4 xx 10^(-4) M "min"^(-1)`
B. `8 xx 10^(-4) "min"^(-1)`
C. `3.3 xx 10^(-4) M "mim"^(-1)`
D. `2.2 xx 10^(-4) M "mim"^(-1)`

Correct Answer - C
Average rate `= (Delta [R])/(Delta t) = - ([R]_(2) - [R]_(1))/(t_(2) - t_(1))`
`= - ((0.04 - 0.05))/(30) = (0.01)/(30)`
`3.3 xx 10^(-4) M "min"^(-1)`
